This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X75S in place of this model. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.

The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X75S is a double-acting profile-type standard cylinder with a Ø63mm bore and 75mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X75S, which matches its bore, stroke, force and mounting.
The AirTAC SUD63X75S is a discontinued double-acting double-rod profile cylinder featuring a 63mm bore and 75mm stroke. A rod exits both ends on a single piston, meaning push and pull force are equal both ways at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The exact drop-in replacement is the SAUD63X75S, matching the 3/8" port, M16x1.5 rod thread, and basic/FA/LB mounting. The SAUD upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here.
This model provides a computed safe working load of about 841 N (60% of the 0.5 MPa force) and can vertically lift roughly 71 kg with a 2:1 margin. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. A plain cylinder does not hold loads on air loss; the 21mm adjustable air cushions only decelerate near stroke end, so an external rod lock is needed for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X75S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAUD63X75S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Drives two opposing conveyor pushes simultaneously using both rod ends, ensuring perfectly synchronized part movement without adding a second cylinder.
The double-rod construction prevents piston rotation during high-speed clamping, maintaining precise angular alignment for multi-axis machining fixtures.
Lifts and lowers a balanced materials jig from both ends, providing equal force both ways to prevent jig twisting during vertical elevation changes.
To replace the discontinued SUD63X75S, use the SAUD63X75S drop-in, matching the 63mm bore, 75mm stroke, 3/8" port, and FA/LB mounting. When sizing both ways, verify the equal-both-ways force fits your needs: 1402 N at 0.5 MPa or 1962 N at 0.7 MPa, or step to neighbour bores (50mm or 80mm). A double rod is right when you need anti-rotation stability or want to drive two tools from one cylinder. For the -S magnet option, change legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For stroke lengths >=300mm, verify side-load limits to prevent guide wear.
Replacement checklist
Yes, the SUD63X75S is discontinued. The exact drop-in replacement is the SAUD63X75S, which shares the same 63mm bore, 75mm stroke, equal force, 3/8" port, and FA/LB mounting. You only need to upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
Because it is a double-rod cylinder, force is equal both ways at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. Operating speed is 30-800 mm/s. The 3/8" port and 21mm adjustable cushions handle deceleration, but an external rod lock is required for load holding.
